Introduction

If you observe any problems inside your scanner, you will have to remove some components to do any work inside your Canon CanoScan N670U.

To reach the inner components of the scanner, you must:

Remove the two side bars that hold the glass scanner bed in place.
Remove the glass scanner bed itself.

Tools

Metal Spudger

Step 1

Open up your Canon CanoScan N670U to an upright position.

Step 2

Turn your device so that you're facing the long side of the Canon CanoScan N670U.
Locate the small crevice between the plastic components of the scanner bed and the scanner base.

Step 3

Carefully insert a metal spudger tool in the crevice and slowly cut through the adhesive between the plastic components.
You may cut small bits of the plastic as you're slicing the adhesive. Do not forcefully bend the plastic strip as you're cutting or it will snap.

This step isn't necessary. The plastic strips are glued to the glass and can stay that way. Simply pull up the front of the strips, slide the glass forwards a little, then pull up the back of the strips and slide the glass backwards, making sure the back ends of the plastic strips slide over the rear plastic panel. Now you can simply lift and slide the glass out from the front, up and forwards. Easy as that! This works because the adhesive isn't applied to the very ends of the plastic strips and because the strips are slightly flexible.
